A new model for the recombination and radiative lifetime of trions and biexcitons in spherically shaped semiconductor nanocrystals
Mehmet Sahin, Fatih Koc
In this letter, we propose a new model to determine the recombination oscillator strength of trions and biexcitons for bound and unbound cases in the effective mass approximation.…
Efficiency of genetic algorithm and determination of ground state energy of impurity in a spherical quantum dot
Haluk Safak, Mehmet Sahin, Berna Gulveren +1
In the present work, genetic algorithm method (GA) is applied to the problem of impurity at the center of a spherical quantum dot for infinite confining potential case. For this pu…
